1. Use for loops
to display the natural numbers from 1 to 50.
## Shell
Script ##
for i in {1..50}
do
echo $i
done
--------------------------------------
for ((i=1; i<=50; i++))
do
echo $i
done
## Python
Script ##
for i in range(1,51):
print(i)
2. Read the
input from user and print.
## Shell
Script ##
read –p “Enter Your Name : ” name
echo “${name}”
## Python
Script ##
name = input(“Enter Your Name : ”)
print(name)
3. Find the largest of three number.
## Shell Script ##
read -p "Enter Num1 : " num1
read -p "Enter Num2 : " num2
read -p "Enter Num3 : " num3
if [ $num1 -gt $num2 ] && [
$num1 -gt $num3 ]
then
echo "Largest number is ${num1} "
elif [ $num2 -gt $num1 ] && [
$num2 -gt $num3 ]
then
echo "Largest number is ${num2} "
else
echo "Largest number is ${num3} "
fi
## Python Script ##
num1 = int(input("Enter Num1 :))
num2 = int(input("Enter Num2 :))
num3 = int(input("Enter Num3 :))
if num1 > num2 and num1 > num3:
largest = num1
elif num2 > num1 and num2 >
num3:
largest = num2
else:
largest = num3
print("Largest number is :
", largest)
4.
Find the given number is prime or not.
## Shell Script ##
read -p "Enter a number: "
num
if [ $num -gt 1 ]
then
for i in `seq 2 $(($num-1))`
do
if (($num % $i == 0 ))
then
echo "$num is not a prime number"
exit
fi
done
echo "$num is a prime number"
else
echo "$num is a not prime number"
fi
## Python Script ##
num =
int(input("Any number number : "))
if num > 1:
for i in range(2,num):
if (num%2)==0:
print(num,"is not a prime
number")
break
else:
print(num,"is a prime number")
else:
print(num,"is not a prime
number")5.
Find the length of string and specific words from the given string.
## Shell Script ##
str="Hello World, This is Testing!"
length=${#str}
echo "Length of str is $length"
echo "Printing the 11 characters starting from 6th position"
echo ${str:6:11}
echo "Printing the 7 characters starting from 21st position"
echo ${str:21:7}
echo "Printing entire string"
echo ${str:0}
## Shell Script ##
str="Hello World, This is Testing!"
length=${#str}
echo "Length of str is $length"
echo "Printing the 11 characters starting from 6th position"
echo ${str:6:11}
echo "Printing the 7 characters starting from 21st position"
echo ${str:21:7}
echo "Printing entire string"
echo ${str:0}
## Python Script ##
str = "Hello World,
This is Testing!"
print("Lenght of
str is ", len(str))
print("Printing
charachetrs from 6th to 10th position ", str[6:11])
print("Printing
charachetrs from 21st to 27th position ", str[21:27])
print("Printing
entire string ", str[0:])
6.
Use for loops to display the numbers from 0 to 50 incremented by 2.
## Shell Script ##
for i in {0..50..2}
do
echo $i
done
--------------------------------------
for i in $(seq 0 2 50)
do
echo $i
done
## Python Script ##
for i in range(0,51,2):
print(i)
